The Curse of Muramasa Blades

Added: 2026-05-20

[00:00:00]They said this sword killed every samurai who ever carried it.

[00:00:06]Not in battle, in their sleep.

[00:00:08]During the Sengoku period, a bladesmith [music] named Muramasa forged weapons so sharp they could split silk falling through the air.

[00:00:18]But something was wrong with his steel.

[00:00:21]Warriors who carried Muramasa blades started losing their minds. One general turned on his own men at midnight.

[00:00:29]Another walked into a river in full armor and never came back up.

[00:00:35]The Tokugawa clan banned every single Muramasa blade after three shoguns in the same bloodline died by them.

[00:00:44]Not by enemies, by accidents. Their own swords cutting them during ceremonies, [music] during practice, during moments no blade should draw blood.

[00:00:54]Soldiers buried [music] them in temple grounds hoping monks could contain whatever lived inside the metal.

[00:01:01]But here is the part nobody talks about.

[00:01:04]Some of those temples burned down centuries later. The swords [music] were never found.

[00:01:09]And some people believe they are still being carried.
